MOTOR-CARRIAGE HOOD.

Application filed January 10, 1925, Serial No. 1,682, and in Germany December 20, 1 923.

My invention relates to a motor-carriage hood having horizontally guided longitudinal kilt hoops. Thishood is distinguished from the known ones essentially by the feature that the rear part of the two longitudinal tilt hoops is connected with the turnahle column and with the bendable rule-joint or coach joints by a guide lever connection in such a manner that the longitudinal tilt hoops are guided not only parallelly, but participate in the movement of the turn able column in conjunction with the bending movement of the rule-joint or coach-joint, whichlatter is bent automatically by means of a spring acting in a telescope-tube and engaging the rotatory head'of the ruleoint or coach-joint, as well as the toot-member of this joint, said automatic bending taking place when the front hood tilt hoops are being lifted.

Collapsing the hoodis effected after the trout longitudinal tilt hoops have been litted, preferably and most conveniently by a pull in rearward direction. There are provided for this purpose one or several straps which engage the front transverse tilt hoop and extend over the hood.

As it is unnecessary to provide a middle carrying rod for the hood, a particularlyreliable hinge-joint must be providedbetween the front and the rear partsof the longitudinal tilthoops. This hinge-joint or hingeconnection is, according to this invention, so devised that the tilt hoops cannot bend through when the hinge-members are directed downwardly, whereas when the hinge members have been turned through 180 the front longitudinal tilt hoop can be turned upwardlyupon that hinge. i

The invention is illustrated diagrammatically and by way of example in the accompanying drawings, in which Figure 1 is a perspective illustration of amotor'carriage provided with my improved hood; which is shown in closed state; Figure 2 is a longitudinal section through the closed hood, combined with a side-view of the appertaining mechanism, this figurebeing drawn to a greatly enlarged scale relatively to Fig. 1;

' Figure?) is a side-view of the same mechanism, partly collapsed, and Figure 4 shows it completely collapsed; Figures 5 and 6 are separate views of the tilt hoops in two pos1- tions, these figures being drawn toa still more enlarged scale; Figure 7 is a separate view of the hinge of the longitudinal tilt hoop, the hinge being shown in section; Figure 8 is a plan of this joint; and Figures 9 and 10 show details which are fully described hereinatter.

1 denotes the body of the carriage, 2 the rear part of the body; this part is shaped similarly toa box or chest, as usually, 3dedenotes the angular body member of a hinge 4, to which is jointed. a bar 5, the lower part :5 of which is bent angularly, as shown. 6 1s a bell-crank lever which is pivoted to the column and. one end. of which is connected with the upper part 8 of the rule-joint or coach-joint 8, 10 by means of a. link 7. The members 8 and 10 of the rule joint or coach oint are connected with one another in known manner by a hinge 9 andcan, therefore, be bent relatively to one another, and the member 10 is hinged, atthe point 11 to a fastening member 11. 12 denotes a telescope-tube spring whichis jointed movably to the rule joint or coach joint member 10 at the point 12 and to .an angular member 13 at the point 12 The object of said telescope-tube spring is to bend the rule-joint or coach-joint automatically when a pressure is exerted on said angular member 13v which is hinged at the point 1% to a lateral projection of the rod 5.

The other leg of the bell-crank lever 6 is connected with another bell-crank lever 17 by means of a rod 16. The lJQllrCI'flnk lever 17 ispivoted to the bodymember 18 which is firmly connected with the column5. 19 denotes the pivot of said lever 17 this pivot serves also as a support for the longitudinal, tilt hoop 20. This tilt hoop and the front tilt hoop 21 are connected with one another by a hinge 22 and by an arrangement and combination of rods resembling Nuremburg scissors. The members 23, 9.4L of the Nuremberg scissors are connected with one another, by a bolt 25 and the member 23 is connectecLbcsides, with the longitudinal tilt hoop 21 by the pivot 26. The rod 15 engages the scissoiwmember 24: between the pivots 25 and 27 whereby a pressure is exerted upon the angular member 13 when the front tilt hoop is being lifted. The free ends of the S018 sor members 23 and 24 carry the transverse tilt hoops 28 and 29 upon which the hood 30 is mounted in known manner, whereas an arm 31 attached to the rear part of the hood and connected movably with the hinge-memproper exterior invention andI abstain, therefore, from entering into details concerning it. t

One strap 33 extends, or several straps 33 extend, longitudinally over the hood 3O they may be coupled loosely with the hood by guide loops(not shown) or the like. The frontend of each strap 33 is connected with the front transverse tilt hoop and the rear end of each strap 33 is connected with the rear rim or edge of the hood (Fig. 1).

The hinge 22 which connects the longitudinal tilt hoops 20 and 21 with one another consists (Figs. 7%10) ot' flat hinge-members 34 connected byscrews with sleeves 35 which are flattened on their top face 9 and can be turned onpivots 36 connected y U- shaped members 37 with the tilt-hoops 20 and 21. Nuts 38. locked by split-pins hold the sleeves'35 securely in place upon the pivots 36. '39 denotes abutment ledges provided on the sides of the tilt-hoops 20 and 21 (Fig. 8); the ends of said ledges project and serve as abutments for the lateral faces of the sleeves35 when these latter are in their upper and lower end-positions. The manner of operation of the entire arrangement and combination of parts described is as follows: a

WVhile the hood is in its open position the longitudinal tilt hoop 20 and the longitudinal tilt hoop 21 which forms an extension of the former is carried by the bell-crank lever 17, without any other support, said lever being rigidly connected by the lovers 16, 6, 7

with the member 3 of the rule-joint or coachjoint 8, 10. To collapse "the hood it is suiticient to lift the front longitudinal tilt hoop, the scissors formedby the members 23, 24- beingv thereby opened and this motion is transmitted to the rule-joint or coach-joint 8, 10 by thebar 15 and the angularmember 13. The rule-joint or coach-joint is thereby bent, as shown in Fig. 3, by the telescopetube spring 12 whereby its. member 8 is moved to the rear. The supporting column 5 and the member 13' connected therewith participate in that movement in that they are actuated by the connecting link? and the bell-crank lever 6, the member 13 turning on its pivot or hingelst. Owing to this turning of this member and to the simultaneous turning of the membersS, 10 the bell-crank lever 6, the rods 16 and the bellcrank lever 17 connected therewith are moved in such a manner that the longitudinal tilt hoop 20 is drawn rearwards, but is held fast duringthis time in horizontal position. It is,'therefo re, not possiblethat the front end of thetilthoop 20 can] (as with the known devices)".turn downwards and knock upon the side-parts of the carriage body whereby these parts can be damaged and, besides, special auxiliary means must be provided to open and close the hood. On pressing the hood further rear-wards the longitudinal tilt hoop 21 is turned down upon the tilt hoop 20 and moved down upon the body-member 18 which then rests upon the column 5. In the spacebelow this latter the bent rulejoint or coach-joint 8, 10 and the member 13 are received. it

Collapsing thc hood rcarwardly is effected in the most convenient manner by pulling rearwardlythe strap or straps 33 after the trout longitudinal tilt hoop has been lifted.

The hood tarpaulin falls freely rear-wards when the tilt hoops are being caused to collapse and can be rolled up and attached to the ca1-riagebythe strap or straps 33 or by any other suitable means.

Concerning especially the manner of o oration of the hingc-connection between tie longitudinal tilt hoops 20 and 21 the following explanations will facilitate understanding it.

hinge 22. If, however, the sleeves 35 are turned"together with the hinge-member 324 through 183 on the pivots 36 so that the hinge 22 then liesbelow the tilt hoops, the arrangementand combination otthe parts described prevents the hinge 22 from bend ingthrough downwardly which is very important and one of the characteristic features of the invention. As the entire hood construction carriedfreely by the lever 17 no middle supporting column is any more necessary. The lateral abutment ledges 39 facilitate the adjustment of the hinge members 3% in its two end-positions. t i

The technical advantages attained by the invention consist essentially therein that the longitudinal tilt hoops are guided parallelly without separate supporting columns when the hood is opened and closcdyand are carried rearwards sofar that thecarriage body windows are not obstructed by the body members 18, in consequence whereof thenccupants oi the carriage have, when the hood is collapsed, a more unobstructed viewthan with the known hood supports employed in connection with motor-carriages, also from the reason, as no middle supports are necessary, as already stated. The longitudinal tilt hoops are carried freely owing to the existence of their particular lever connection' 8, 7, 6, 16, 17, "and they are secured against bending throughby the hinge-joint 22, in connection with the parts denotcd The lever connection 7, 6, 1 6 ensures the parallel guiding of the longitudinal tilt :1? the hinge-mei'nbers 3% which are screwed together with the sleeves 35 are situated above the tilthoops it is possible to turn the tront tilt hoop towards the rear one on the hoops when the hood is opened and collapsed, so that the front end thereof cannot fall down.

Finally, opening and closing the new hoodsupporting structure can be effected easily byonly one attendant as, owing to the automatic bending through of the rule-joints or coach-joints 8, 10 when the front longitudinal tilt hoops are lifted, it is no more necessary to bend them through manually so that a pull from the rear exerted on the straps 33 is suiiicient to collapse the hood. Ito-closing it is assisted efiectually by the telescope-tube springs 12 which when the hood is collapsed are put under a tension of such strength that they, after having got past the position shown in Fig. 4, tend to lift the hood and to open it. p
